Description

температуре менее нижнего предела резко возрастала величина сопротивлени  металла деформации, при величинах обжати  по диаметру менее 45% и по толщине стенки менее 72°/о не обеспечивалась требуема  точность геометрических размеров и необходима  проработка структуры, а при обжатии по диаметру более 55% и по толщине стенки свыще 86% происходило значительное возрастание величины сопротивлени  деформации.temperature less than the lower limit sharply increased the amount of metal deformation, when the values of reduction in diameter less than 45% and wall thickness less than 72 ° / o did not provide the required accuracy of the geometrical dimensions and necessary to work out the structure, and when compression in diameter more than 55% and thickness walls of 86% sveyshche there was a significant increase in the amount of resistance to deformation.

Пример осуществлени  способа.An example of the method.

Пола  заготовка размером 173 65х350 мм из сплава, содержащего железо никель, кобальт и молибден, типа ОЗН18К8М5ТЮР была подвергнута гор чей обработке давлением на трубопрофильной установке усилием 1600 тс при температуре 1180°С с обжатием по диаметру 51% и по толщине стенки 78% с использованием стеклосмазки. Размер труб после прессовани  мм. Удаление стеклосмазки произведено в щелочном расплаве при температуре 375°С.A 173 65x350 mm billet made of an alloy containing iron, nickel, cobalt and molybdenum, type OZN18K8M5TYUR, was subjected to hot pressure treatment at a pipe-profile installation with a force of 1600 tf at a temperature of 1180 ° С with a reduction in diameter of 51% and a wall thickness of 78% using glass lubricants. Pipe size after pressing mm. Removal of glass grease produced in an alkaline melt at a temperature of 375 ° C.

Таким образом, прочностные свойства металла труб, изготовленные по предлагаемому способу, выще по сравнению с известным .Thus, the strength properties of the metal pipe, made by the proposed method, higher than in the known.

Одновременно отмечено увеличение точности геометрических размеров по толщине стенки примерно на 5-10%. Применение предлагаемого способа позвол ет повысить качество труб из сплавов, содержащих железо , никель, кобальт и молибден, путем повыщени  точности геометрических размеров и увеличени  прочностных свойств на 4-6%At the same time, an increase in the accuracy of geometrical dimensions along the wall thickness by about 5-10% was noted. The application of the proposed method allows to improve the quality of pipes from alloys containing iron, nickel, cobalt and molybdenum, by increasing the accuracy of geometrical dimensions and increasing the strength properties by 4-6%
